Corsa Performance Xtreme Catback systems are designed and engineered to give your Coyote powered S550 Mustang an aggressive tone under acceleration and a deep growl at idle while minimizing interior cabin drone. This Corsa Xtreme Catcack will greatly improve your Mustang's exhaust flow and provides a considerable increase in overall power. 


The included Corsa X-Pipe for the S550 GT Mustang's not only helps improve exhaust flow for an increase in power, but with its modern double helix "X" crossover design it also adds a crisp raspy, race type growl to the sound of your exhaust. 


Corsa designs their mufflers using their own patented Reflective Sound Cancellation® Technology (RSC™) to give your Mustang an aggressive sound under acceleration and a drone-free experience while cruising.


Corsa catback systems are manufactured in the USA from 3.0" diameter premium grade 304 stainless steel tubing for a improved exhaust flow and a perfect fit. The system includes a double helix X-pipe and features two straight-through mufflers that end with polished 4.5" Pro-Series tips. This 3" catback also includes step down flanges so it can be installed with the stock 2.5" exhaust.


This Corsa Xtreme Cat-Back Exhaust System with Polished Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and the 2018 Fastback GT Mustangs that is not equipped with the Active Exhaust System.

The 2015-2017 Model Years will require the use of the Roush Rear Valance for proper installation (valance sold separately). Does not fit convertible models.
